What are all the parts necessary for a decent fuel upgrade. I dont wanna do little by little, i want to get most of if not all of it done in one shot.

Injectors
fuel rail
fpr (does this need to be upgraded?)
fuel filter...

 

in order to tune the fuel it does. i changed everything north of the firewall in the back to earls performaflex shiiit. i also recomend getting a pump. that should do you on the fuel unless you wanna earl it back to the tank which is overkill until you need it
